EMD F40PH2 Locomotives /
F40PH2
When CSX wanted units to replace the aging F-units to run their Business trains, they looked to the ex-Amtrak F40s. Two were acquired initially (9992,9993, then two more followed a few years later (9998,9999).

EMD GP7 Locomotives /
GP7
Four GP7s made it to the CSX roster, all from the Seaboard side. CSX GP7 2302 stayed on the computer long enough to require a gap in the numbers for the 2nd order of RDMT units, stopping at 2301 and resuming with 2303.

EMD GP9 Locomotives /
GP9
Even though many GP9s were still sitting around shops at the time CSX was formed, only 7 actually received their CSX number. All of these were ex-Chessie, 6 coming from both the B&O and 1 from the C&O.

EMD GP15-1 Locomotives /
GP15-1
CSX rostered 42 of these units, all ex-conrail acquired from the Conrail split-up. Many were returned when their lease expired shortly after CSX got them.

EMD GP15T Locomotives /
GP15T
All of the CSX GP15T units wre ex-C&O, acquired by the Chessie System in 1982. There were only 28 ever made, and Chessie purchased 25 of them. Just about all of these units have worn multiple CSX paint paint schemes.

EMD GP16 Locomotives /

CSX rostered 161 of these rebuilt units. The first few done were rebuilt at the IC Paducah, KY shops and some consider GP11s. The rest were rebuilt by the Seaboard's Uceta shops in Tampa

EMD GP18 Locomotives /
GP18
The SCL and the L&N each contributed one GP18 to the CSX roster. Those are the only two CSX had and both seemed to hang around Radnor Yard in Nashville before disappearing from the roster.

EMD GP30 Locomotives /
GP30
The CSX GP30s came from both the Chessie (29) and Seaboard (7) sides of CSX. Only two ever received a coat of CSX paint as GP30s. However, many were rebuilt into RDMT slugs and painted then.

EMD GP30M Locomotives /
GP30M
The 67 GP30Ms were all from the Chessie. These were B&O and C&O GP30 units that went through Chessies rebuilding program at both the Huntington and Cumberland shops. After rebuilding Chessie did not renumber the units, but CSX decided to give them their own number series.

EMD GP35 Locomotives /
GP35
The majority of the GP35s on the CSX roster were former Chessie units (B&O, C&O and WM). There were a few former Seaboard units and later 3 RF&P units came on board. Only a handful received CSX paint and many ended up as road slugs.

EMD GP38 Locomotives /
GP38
Coming from a wide variety of predecessor roads, the GP38 was a common unit on CSX. Near the end of the useful lives, 19 were repainted into the MofW pumpkin scheme and renumbered 9650-9668.

EMD GP38-2 Locomotives /

EMD GP39 Locomotives /
GP39
All 20 of CSX's GP39s were built for the C&O back in 1969 and came delivered in their enchantment blue paint. All were repainted Chessie before the start of CSX. Most of their CSX era was spent as mother units mated to yard slugs.

EMD GP39-2 Locomotives /
GP39-2
Rare to CSX, this was a model not owned by CSX, Seaboard or Conrail. Chessie helped with the financing of these units back when they were purchased, and they eventually found their way back to CSX in a variety of unique paint schemes.

EMD GP40 Locomotives /

GP40s were plentiful in the early days of CSX. Chessie B&O, C&O, WM contributed , along with the Seaboard roads. Later, 7 RF&P units joined the ranks. There were GP40s "pupkinized" (31) than any other model.

The signature model of the Chessie System, who purchased more GP40-2s than any other railroad (348). Seaboard System, Conrail, RF&P all contributed units as well. Many were renumbered into the 6400s and 6900s and converted to mother units for road slugs.
